Sinà Âiju (; ) is a city in North Korea which faces Dandong, Liaoning, China, across the international border of the Yalu River. It is the capital of North P'yà Ângan province. Part of the city is included in the Sinà Âiju Special Administrative Region, which was established in 2002 to experiment with introducing a market economy. In recent years the city has seen increasing tourism from China.
Sinà Âiju is bordered by the Amnok River, and by P'ihyà Ân and Ryongch'à Ân counties. The city's altitude is 1 metre (4 feet) above sea level. There are several islands at the mouth of the Amnok River - Wihwa-do, Rim-do, Ryuch'o-do and Tongryuch'o-do.
Sinuiju city is the heart of the Sinuiju Special Administrative Region. The city is currently divided into 49 tong (neighbourhoods) and 9 ri (villages):
Developed as a major settlement during Japanese colonial rule at the terminus of a railway bridge across the Amrok River, Sinuiju is located 11 km (7 miles) south by southwest of à ¬iju, the old city from whose name Sinà Âiju (meaning âÂÂNew à ¬ijuâÂÂ) derives. As an open port, it grew commercially with the logging industry which uses the Amnok River to transport lumber. Additionally, a chemical industry developed after the hydroelectric Sup'ung Dam was built further up the river.
During the Korean War, after being driven from P'yà Ângyang, Kim Il Sung and his government temporarily moved the capital to Sinà Âiju - although as United Nations Command forces approached, the government again moved - this time to Kanggye. On 7 November 1950, the city sustained heavy damage during an aerial bombardment from the United States Air Force; 95 percent of the city was destroyed. However, the city has since been rebuilt.
In 2018, a master plan for the redevelopment of the city was unveiled and shown to Kim Jong Un, which would have featured many high rise buildings and parks, centered around the road leading to the statues of Kim Il Sung and Kim Jong Il. Ultimately, this plan has yet to be fulfilled, with the only major work completed being the repaving of roads leading to the statues and the red coloured, circular apartment building behind and the Sinuiju Youth Open Air Theatre's completion, although the industrial areas in the city have seen some reconstruction.
An important light industry centre in North Korea, Sinà Âiju has a plant manufacturing enamelled ironware as well as a textile mill, paper mill and an afforestation factory. Its southwest harbour has a shipyard, although the shipyard's main function is seemingly to dismantle ships for scrap metal and other usable materials rather than building new ships. The area has recycling plants which recycle a wide range of material, including products that are banned for recycling in China. The Sinà Âiju Cosmetics Factory is located in South Sinà Âiju (Namsinà Âiju).
A substantial portion of North Korea's international trade, both legal and illegal, passes through Sinuiju and Dandong, across the Yalu River.
Sinà Âiju can be reached from P'yà Ângyang by air, railway, and road. It can be reached from Dandong in China by crossing the Amnok River by bridge or boat. Foreign tourists on excursion boats from Dandong are sometimes permitted to approach within a few meters of the city's coastline, as long as they do not land.
Sinà Âiju's airport has a single turf runway 03/21 measuring 991 metres by 61 metres (3250 feet by 213 feet). Air Koryà  operates passenger and cargo flights from P'yà Ângyang.
Sinà Âiju Ch'à Ângnyà Ân Station is the northern terminus of the Korean State Railway's P'yà Ângà Âi Line from P'yà Ângyang; the district is also served by several other stations on the P'yà Ângà Âi line, as well as the Tà Âkhyà Ân and Paengma lines. It is also connected with the Chinese city of Dandong in Liaoning Province in China by the Sino-Korean Friendship Bridge, which is long from end to end, and through the Manchuria Railway links up with the Trans-Siberian Railway. The factories of the city of Sinà Âiju are provided with railway service via the Kang'an Line.
Sinuiju has a trolleybus line that runs from the city centre to the railway station. It was reopened in October 2020 with new trolleybuses derived from the Pyongyang Chollima-321 trolleybus. It formerly had another line running from the Sinuiju Chongnyon Station to Ragwon Machine Complex that closed between 2005 and 2009 with the reconstruction of the highway with a shifted alignment.
Sinà Âiju has a monsoonal humid continental climate (Köppen Dwa) with hot, humid and stormy summers and cold, dry winters with little snowfall.
Facilities in Sinà Âiju include Sinà Âiju High School, Sinà Âiju Commercial High School, Eastern Middle School, Sinà Âiju Light Industry University, Sinà Âiju University of Medicine and the Sinuiju University of Education. Scenic sites include the Tonggun Pavilion, Waterfall, and Hot Springs.
There also is a Ferris wheel overlooking the Yalu River, reportedly broken.
